Advanced P&O Incremental Conductance Algorithm: By repeatedly disturbing the voltage and testing different sunlight intensities to continuously adjust the charging voltage, the operating point of the solar system charging power gradually approaches the maximum power point, improving the charging efficiency and effectively increasing the charging efficiency by 36%*, ensuring superior performance even on cloudy days compared to non-MPPT chargers
ETFE Anti-solar refraction Material: ETFE's exceptional light transmittance (up to 95%) significantly s solar cell efficiency by optimizing light delivery, making it perfect for a solar car battery charger and solar trickle charger for car battery 12V applications. Its high transparency is maintained long-term, while robust carbon-fluorine (C-F) bonds provide superior UV resistance, preventing embrittent and degradation, and ensuring excellent tolerance to harsh temperatures and corrosion
